E-Park is activated when the driver pushes the PARK
button. An electric motor activates the parking pawl and
locks the single-speed transmission when the vehicle is
placed into PARK. This will prevent any unwanted move-
ment of the vehicle.
NOTE:The engagement of the E-Park can be heard when
there is no noise in the interior of the vehicle, this is a
normal condition.
Climate Control (HVAC System)
Your 500e is equipped with an Automatic Temperature
Control (ATC) HVAC system. This HVAC system utilizes a
humidity sensor, cabin sensor, and ambient temperature
sensor to choose operation mode and control cabin com-
fort. These components allow the controller to operate the
HVAC system in a very efficient manner to maximize
driving range.
Your 500e also uses an electric air heater to provide heat to
the cabin.
Electric Air Conditioning Compressor
Your 500e uses an electric air conditioning compressor. The
air conditioning compressor is powered by the high volt-
age battery system and is used to cool the vehicle occu-
pants and the high voltage battery while the vehicle is
being driven or when it is being charged.
The high voltage battery may require cooling to keep the
vehicle running. The air conditioning compressor activates
without any input from the occupant.
NOTE: The AC system helps cool the high voltage battery.
If the air conditioning system should require service, see an
authorized dealer as soon as possible.
Electric Power Steering
Your vehicle is equipped with an Electric Power Steering
(EPS) system. The power steering system requires no
maintenance and operates without the use of power steer-
ing fluid.

on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to main-
tain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunc-
tion indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approximately oneminute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction
indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function properly.
CAUTION!
The TPMS has been optimized for the original equip-
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.

(BLD), functions similar to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more torque to be applied to the wheel that is
not spinning. This feature remains active even if TCS and
ESC are in the Partial Off mode. Refer to “Electronic
Stability Control (ESC)” in this section for further informa-
tion.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC corrects
for oversteering or understeering of the vehicle by apply-
ing the brake of the appropriate wheel to assist in counter-
acting the oversteering or understeering condition. Vehicle
power may also be reduced to help the vehicle maintain
the desired path. ESC uses sensors in the vehicle to
determine the vehicle path intended by the driver and
compares it to the actual path of the vehicle. When the
actual path does not match the intended path, ESC applies
the brake of the appropriate wheel to assist in counteract-
ing the oversteer or understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position. •
Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
NOTE: The ESC Off switch is located on the instrument
panel.
WARNING!
• The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent all
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent collisions
resulting from loss of vehicle control due to inappro-
priate driver input for the conditions. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of an ESC equipped vehicle must
never be exploited in a reckless or dangerous manner
which could jeopardize the user ’s safety or the safety
of others.

tain your vehicle, may change the handling charac-
teristics of your vehicle, and may negatively affect

the measured tire pressure is 28 psi (193 kPa), a tempera-
ture drop to 20°F (-7°C) will decrease the tire pressure to
approximately 24 psi (165 kPa). This tire pressure is low
enough to turn ON the “Tire Pressure Monitoring System
Warning Light.” Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
Tire Pressure Monitoring System Warning Light will still be
on. In this situation, the Tire Pressure Monitoring System
Warning Light will turn off only after the tires are inflated
to the vehicle’s recommended cold placard pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. The TPM sensor is not designed
for use on aftermarket wheels and may contribute to
a poor overall system performance or sensor damage.
Customers are encouraged to use OEM wheels to
assure proper TPM feature operation.

CAUTION! (Continued)
•Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealership to have your sensor
function checked.
• After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
108 SAFETY

•Under-inflation also reduces the high voltage battery
range and tire tread life, and may affect the vehicle’s
handling and stopping ability.
• It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and
to maintain the proper pressure.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the level
to trigger illumination of the Tire Pressure Monitoring
System Warning Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.TPM System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
The TPMS consists of the following components:
• Receiver module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
• Tire Pressure Monitoring System Warning Light

SAFETY 109

If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the Tire Pressure Monitoring System Warning
Light will no longer flash, and the “Service TPM System”
message will no longer display.
A system fault can occur due to any of the following:
1. Signal interference due to electronic devices or drivingnext to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains ma- terials that may block radio wave signals. 3. Accumulation of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
• The TPMS will not monitor the pressure in a replace-
ment tire installed without a tire pressure sensor.
• If you install a replacement tire in place of a road tire
that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the Tire
Pressure Monitoring System Warning Light will remain
on and a chime will sound. In addition, the highlighted
graphic in the instrument cluster will still display a low
pressure text message and a pressure value in a different
color.
• After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring System
Warning Light will flash on and off for 75 seconds and
then remain on solid. In addition, the instrument cluster
will display a “Service Tire Pressure Monitoring System”
message.

The air bag system must be ready to protect you in a
collision. The Occupant Restraint Controller (ORC) moni-
tors the internal circuits and interconnecting wiring asso-
ciated with the electrical Air Bag System Components.
Your vehicle may be equipped with the following Air Bag
System Components:
Air Bag System Components
•Occupant Restraint Controller (ORC)
• Air Bag Warning Light
•Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
• Seat Track Position Sensors
Air Bag Warning Light
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch
is in the AVV/START or MAR/ACC/ON/RUN
position. If the ignition switch is in the STOP/
OFF/LOCK position the air bag system is not on
and the air bags will not inflate.
The ORC contains a backup power supply system that may
deploy the air bag system even if the battery loses power or
it becomes disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight seconds
for a self-check when the ignition switch is in the MAR/
ACC/ON/RUN position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects a malfunc-
tion in any part of the system, it turns on the Air Bag
Warning Light, either momentarily or continuously. A
single chime will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will illuminate the
instrument panel Air Bag Warning Light if a malfunction is
detected that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction. While the air

WARNING!
•Being too close to the steering wheel or instrument
panel during front air bag deployment could cause
serious injury, including death. Air bags need room
to inflate. Sit back, comfortably extending your arms
to reach the steering wheel or instrument panel.
(Continued)
WARNING! (Continued)
•Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
• Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child re-
straint in the rear seat. If the vehicle does not have a
rear seat, do not transport a rear-facing child restraint
in that vehicle.
Driver And Passenger Front Air Bag Features
The Advanced Front Air Bag system has multistage driver
and front passenger air bags. This system provides output
appropriate to the severity and type of collision as deter-
mined by the Occupant Restraint Controller (ORC), which
may receive information from the front impact sensors (if
equipped) or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions.

This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether the
driver or front passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of the Ad-
vanced Front Air Bags.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
WARNING!
•No objects should be placed over or near the air bag
on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.
• Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
the air bags and you could be injured because the air
bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.
(Continued)
WARNING! (Continued)
•Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some
collisions, air bags won’t deploy at all. Always wear
your seat belts even though you have air bags.
Front Air Bag Operation
Front Air Bags are designed to provide additional protec-
tion by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions. The front air bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not
good indicators of whether or not an air bag should have
deployed.
